Sealing Sandstone

Renovating a large Sandstone Floor in Disley

This is a large 17.2 m2 Sandstone Floor installed throughout the living and kitchen areas of a property in the beautiful village of Disley close to Lyme Park which is run by the National Trust. The floor had been installed four years ago and my client was unhappy with the original sealer which hadn’t lasted very long. Without the protection of a sealer dirt had become ingrained in the pores of the stone which was now difficult to clean. Another issue was the rough nature of the Sandstone meant it was impossible to mop as it shreds the mop! As a result, the floor was mainly cleaned with a hoover which was not ideal, especially in a kitchen.

I went over to survey the floor and before quoting I ran a small test clean in the kitchen which took the floor back to its natural pale colour and really showed how dirty the floor had become. Test cleans are great as it helps me to formulate an effective cleaning plan and provide an accurate quote. My client was impressed with the result and so I was booked to come back and deep clean and then reseal the whole floor. Due to its size I estimated the floor would take two days to deep clean and a further day to apply a new sealer, so three days in total.

Deep Cleaning and Restoring a Sandstone Tiled Floor

Working in large sections I started by cleaning the floor and stripping off the old sealer with a strong dilution of Tile Doctor Remove and Go which is a coatings remover that is safe to use on stone. The solution was left to soak into the pores of the Sandstone for ten minutes before being worked in with a 200-grit diamond pad fitted to a rotary floor machine. This action not only removed the old sealer and cleaned the floor but the 200-grit pad being vey coarse removed a lot of the roughness from the surface of the Sandstone so it shouldn’t shred any more mops.

After rinsing the floor with water and removing the slurry with a wet vacuum I set about cleaning the grout with Tile Doctor Pro-Clean worked into the grout line with a stiff brush and assisted with steam from a professional steam cleaner with a grout attachment. Once done the floor was rinsed and extracted again to remove the soil from the grouting. There was also an area near one of the doors where the grout had become loose and needed replacing so I made up a batch of matching grout and filled this in. The floor was then left overnight to dry with assistance from a couple of air movers.

I returned the next day to finish the floor by applying a sealer. First, I double checked the floor was dry with the damp meter. The readings confirmed the air movers had done a good job and that the floor was within the accepted parameters, so I was ready to seal. The sealer I chose was Tile Doctor Seal and Go which being water based doesn’t leave a smell as it dries, it really works well on Sandstone and adds a nice subtle sheen to the stone.

Once finished the floor looked much cleaner, lighter in colour overall more inviting, you could even see the fossils in some of the tiles.

The surface was also smoother so the customer should find cleaning with a mop much easier in future. On that subject its worth pointing out that owners of sealed floors should always use a neutral pH tile cleaner on their floors as most supermarket products are simply too strong and will prematurely strip the sealer off a tile if used repeatedly. Tile Doctor sell a product called Tile Doctor Neutral Cleaner which is ideal for cleaning sealed Sandstone floors like this one.

My client was really happy with the results and sent me a message later saying: “the floor looks amazing!”
